Ammonium (NH\u2084\u207a) is an important Reagent for water quality and is produced by microbial decomposition of organic material or enters the water through fertilizers, wastewater and agricultural inputs. An increased ammonium concentration can indicate contamination and must be monitored critically, especially in drinking water, aquariums and fish farms. <\/p>\n
The limit value for drinking water in Germany is 0.5 mg\/l NH\u2084\u207a<\/strong> (Drinking Water Ordinance). In bodies of water, ammonium serves as a nutrient for algae and plants, whereby increased concentrations can lead to eutrophication. Ammonium is toxic to fish – even small amounts can cause gill damage. <\/p>\n Ammonium control is essential in aquariums, as ammonium is first broken down by bacteria to nitrite and then to nitrate in the biological balance of the aquarium. Regular measurement protects fish from poisoning and provides information on the functionality of the biofilter. <\/p>\n The CALDUR\u00ae Ammonium Test Set – Photometric is based on the high-precision indophenol blue method. After adding three reagents to the water sample, a characteristic blue-green coloration develops within 8 minutes, the intensity of which is proportional to the ammonium concentration. <\/p>\n The evaluation is carried out photometrically using the WINLAB Data Line photometer, which enables a particularly precise measurement in the low concentration range. The method is highly specific for ammonium and exhibits only minimal cross-reactions with other nitrogen compounds. <\/p>\n Ideal for regular checks in aquariums, fish ponds and sewage treatment plants – immediate results<\/p>\n<\/li>\n Optimized for drinking water and aquarium applications with maximum accuracy<\/p>\n<\/li>\n Cost-efficient for daily checks in aquaculture, waterworks and environmental analysis<\/p>\n<\/li>\n Objective measurement results without subjective color assessment<\/p>\n<\/li>\n Precise measurement results even with complex water matrices<\/p>\n<\/li>\n Economical refill for continuous use<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":" CALDUR\u00ae Ammonium Test Set – Photometric What is ammonium measured for?
